Streamlining Endoscopy Cleaning: The Impact of a New Detergent on Time and Water Use

Reprocessing reusable flexible endoscopes is resource-intensive and involves high water consumption. This study evaluated the impact of replacing a standard detergent with EndoPreZyme™, a novel detergent, at Blackpool Teaching Hospitals NHS Foundation Trust. We assessed manual cleaning times, water usage, costs, and technician experiences. A direct observational time system analysis was conducted over two one-week periods to record technician tasks before and after implementing EndoPreZyme™, allowing for the omission of the final rinse after manual cleaning. Technician surveys captured user experiences during the transition. The results showed that removing the final rinse after manual cleaning reduced water consumption by 25 litres per endoscope, resulting in an estimated saving of 725,000 L annually. The average manual cleaning time decreased from 13 min 10.2 s to 11 min 10.7 s-a reduction of 1 min 59.5 s per endoscope (15%). This efficiency gain translated to approximately 962.9 fewer technician hours being required annually for manual cleaning. Cost analysis revealed a slight per-endoscope cost reduction (GBP 4.88 vs. GBP 4.90). Technicians reported improved productivity, reduced workload, and an awareness of water conservation. These findings demonstrate that EndoPreZyme™ supports NHS sustainability goals by decreasing water usage and enhancing operational efficiency in healthcare delivery.
